Which statement is incorrect regarding the rise of Other Backward Classes (OBC) as a political force in India at National level?

The rise of OBC-oriented parties began with Congress's support.

The correct answer is Option 4 - The rise of OBC-oriented parties began with Congress's support.

Option 4 is incorrect as the rise of these parties (OBC-oriented parties) first found political expression at the national level in the form of the Janata Party government in 1977 not Congress.

Explanation :

One long-term development of this period (1980s and 1990s) was the rise of Other Backward Classes as a political force. The term ‘OBC’ refers to the administrative category ‘Other Backward Classes’. These are communities other than SC and ST (Option 1) who suffer from educational and social backwardness (Option 3). These are also referred to as ‘backward castes’ (Option 2). We have noted that the support for the Congress among many sections of the ‘backward castes’ had declined. This created a space for non-Congress parties that drew more support from these communities. You would recall that the rise of these parties first found political expression at the national level in the form of the Janata Party government in 1977 (CORRECT VERSION OF OPTION 4). Many of the constituents of the Janata Party, like the Bharatiya Kranti Dal and the Samyukta Socialist Party, had a powerful rural base among some sections of the OBC.
